Answer:
c is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
Answer:
6x^2 − 10x − 24
Step-by-step explanation:
2(3x + 4)(x - 3)
(6x + 8)( x − 3)
6x^2 − 18x + 8x − 24
6x^2 − 10x − 24
Multiply the first equation by 2 to then use elimination by adding the 2 equations.
So, 14x-2y=14
+. x+2y=6
Equals 15x=20 so x=20/15=4/3
Plug in to first equation to get y
7(4/3)-y=7
28/3-y=7
28/3-y=21/3
So y=7/3
Plug both x and y into second equation to check
4/3+2(7/3)=
4/3+14/3=18/3=6 it works
So x=4/3, y=7/3
Hope this helps! Have a blessed day!
Answer:
x = -9, -2, and 3.
just set everything possible to 0.
since 0 = 0 it must be true.
